DAVID S. KENNEDY, OF BROOKLYN, NEW YORK, SSIGNOR TO MERGENTHALER LINOTYPECOMPANY, A CORPORATION 0F NEW YORK.

TYPOGRAPHICAL MACHINE.

Specification of Letters Patent.

Patented Oct. 26, 1915.

To all whom t may concern Be it known that I, DAVID S. KENNEDY, a citizen of the United States, and a resident of Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement in rlypographical Machines, of which the following is a specification.

My invention has reference to typographical machines, such as linotype machines of the general organization represented in Letters Patent of the United States, No. 436,532, to @.Mergenthaler, wherein circulating matrices are released from a magazine inthe order in which their characters are to appear in print and then assembled in line together with expanding spacers, the composed line transferred to the face of a mold, the mold filled with molten metal 'to form a slug or linotype against the matrices which produce the type characters thereon, and the matrices thereafter elevated and re turned through a distributing mechanism to the magazine from which they started.

More particularly the invention relates to that class of linotype machines in which a magazine or series of magazines is mounted on a frame which may be shifted upward and downward, as shown in Letters Patent of the United States, No. 859,618, to John R. Rogers, and even more specifically in his application for Letters Patent, Serial No. 624,426, tied May 1, 1911.

The main object of the invention is the provision of means wherebyone or more movable magazines may be shifted to and from operative position by power actuated devices, instead of manually as in the said Rogers patent and application. ATo this end l employ hydraulic apparatus, which is preferably operated by a powerdriven member of the machine; andinjaddition to this generic feature I have devised various details and features of construction which are peculiarly advantageous in the `general organization.

In the accompanying drawings I have shown my mechanism and apparatus in aprefer-red form, but obviously many changes and variations may be made therein which will still be comprised within its spirit; and, generally speaking, I desire it to be understood that it is not limited to `any specific form or embodiment 'except Vinso far as such limitations are specified inthe claims.

Referring to the drawings: Figurel is a side view of a portion of a linotype machine having my invention applied thereto; Fig. 2 is a transverse vert-ical section through the hydraulic pump; and Fig. 3 is a vertical section taken substantiallv on the line 3 3 in Fig. 2.

Referring to the drawings, the general arrangement of the parts is substantially similar to that illustrated in the before-mentioned Rogers application, No. 624,426. The movable magazines A are mounted in the shift frame B, to which is connected the elevating member C, which in the present instance is in the form of a hydraulic piston mounted in the pressure cylinder D. The fluid, such as oil, or the like, is forced into the cylinder D beneath the piston C through. the pipe E by the pump plunger H, which is reciprocated in the ordinary manner in the pump chamber Gf. The oil or ether fiuid is stored in the reservoir R and is drawn therefrom through the pipe F to the chamber G, the pipes E and F being provided respectively with the springpressed inlet and outlet valves El and F1 in the manner well understood in the art. The pump plunger H receives its reciprocating movement from the eccentric strap H1 and eccentric H2 mounted upon the customary intermediate shaft J, which is constantly rotated as in tbe ordinary commercial linotypeV machine. The eccentric H2 is loosely mounted upon the shaft d and in immediate proximity to the member J1, arranged to rotate with the shaft J and capable of longitudinal movement thereon, so that it may be thrown into and out of contact with the member H2, thus constituting a friction clutch. The engagement and disengagement of the pump and shaft are controlled from the hand-lever K3 pivoted at Kt, and connected by the link lf2 to the clutch lever K, which is pi'voted at K5 and engages with a circumferential groove in the clutch member J1, in such manner that the movement if the hand-lever effects or breaks the clutch connection. at will. lVhen the clutch is open the shaft J rotates without effect upon the hydraulic apparatus, and when closed the pump plunger H is actuated to force the fluid into the cylinder D, and thereby the piston C, shift frame B, and magazine or magazines A will be elevated. The `return or downward movement of the frame B and lmagazine or magazines A is effected by gravity upon relieving the pressure in the Y cylinder D and permitting the fluid therein its spring.

to return to the reservoir R. The means for effecting this last result are constituted by a by-pass arrangement now to be described.

The pipe E is connected Vthrough an intermediate pipe L vvith the chamber M, from Which in turn the return pipe L1 leads to the reservoir R. Between the pipe L and chamber M is mounted a spring-seated valve M1, Which in the normal operation of the pump remains closed due to the pressure of The valve IV 1 is provided with a stem M2, in positionv to be engaged by the arm K1 of the clutch lever K. Vhen the hand-lever K3 is operated to disconnect the clutch member J 1Vfrom the member H2, it is swung about its pivot ITS, and the outer end of the arm K1 is elevated, thereby lifting the valve M1 from its normal position.V This permits the return of the fluid from the cylinder D through the pipe E, pipe L, chamber M, and pipe L1, to the reservoir R. The piston C is now free to descend in the cylinder D, and similarly this permits the return movement of the shift frame B and the magazine or magazines A by gravity, when the latter are unlocked in the manner hereafter to be described. The valve Ml subserves anV additional function as a safety appliance or relief valve. The pressure of its spring is ordinarily sufficient to maintain it in its seated or closed condition, but in the event of an obstruction to the shifting of the magazines, or of other undue resistance, the valve N 1 Will yield and relieve the strain, notwithstanding the continued operation of the pump plunger H. TWhen the magazine or magazines A are shifted to the desired location, they are registered and retained therein by locking means substantially the same as those described in the before-mentioned Rogers application. These means comprise one or more locking bars N, Which enter and engage the'locking notches N2 upon the shift frame, the bars being normally urged into the locking position by springs N1. In the Vpresent instance, when the magazines are shifted in the manner previously described and reach the proper position, the bars N Will be forced into the vnotches N2 which then re istery therewith thereby holding the shift frame and magazines firmly against movement. In the event that the pump continues its action after the magazine movement is arrested, so as to cause undue pressure in the'cylinder D, the valve l 1 Will yield to relieve it in the manner above noted. In order to shift the magazine or magazines to another position, the locking bars N must be `first removed from the notches N2, and this is effected in substantially the same manner as in the said Rogers application, namely, through the pivotedhand-lever O, link O1, level" O2, link O3, lever O4, link O5, arm O6, rock shaft O7, and arms O8, which latter act to retract the locking bars N.

As previously stated, my invention has been herein shown in preferred form, but obviously many changes and variations in its construction and mode of application will suggest themselves to those skilled in the art Without departure from its scope.

Having thus described my invention, its construction and mode of operation, what I claim and desire to secure by Letters Patent of the United States is as follows:

1. In a typographical machine, the combination of a magazine, pressure-Huid apparatus acting With a yielding pressure to shift it into and out of operative position, and means for controlling said apparatus.
